The Eurovision Song Contest is an annual showcase of songs, running since May 24, 1956 and broadcast on television (but mainly radio in the first few years) throughout Europe. More recently, it has also been shown in other parts of the world and on the internet.

Initially each country was allowed to submit two three-minute (or less) songs, performed by inhabitants of the respective country. By the 1960s, entries were limited to one song per country (participation in the contest had almost doubled), and the songs had to be sung in one of the national languages of the country. Participation continued to grow through the 1980s, and by the turn of the century the rules had been changed several times to both limit the number of finalists and to allow for the new independent republics that arose from the former Eastern bloc nations.

Current rules state, that countries are only allowed to have six performers on stage and that performers must be aged 16 or more, on the 31st of December in the year of the contest. It is worth noting that due to the current rules there is no restriction on the nationality or the language of the performers, allowing the Australian Olivia Newton-John, for instance, to represent the UK in the contest, and Celine Dion to represent Switzerland, amongst many others. Many small countries sing in English to reach broader, though, in bigger countries, this is looked at as unpatriotic. If a EBU country does not broadcast the Song Contest they are automatically disqualified for the next year.

Up until 2003 entry to the Eurovision song contest also requires the country to have performed with a reasonable amount of success for the previous few years. France, Germany, Spain and the UK automatically qualify.

At the beginning of 2003 the European Broadcasting Union (EBU) decided to make the Eurovision Song Contest a two day event as from 2004. This means that the previous restrictions for countries to participate will be dropped. Any EBU member country will be able to participate in any given year.

The winner of the contest is decided by each country assigning points (currently 1 to 8, 10 and 12) to their favourite ten entries. In some countries, phone polls are held during the telecast in order to decided how the country should award its points. Countries are not allowed to vote for themselves.
The conductors do a round of satellite connections to the speaker for each country jury, that proceeds to read their votes. Then the conductors repeats them in English and French, using this stereotyped structure: "Country name, number points. Nom du pays, nombre points"

Hosting the Eurovision Song Contest is an honour accorded the winners of the previous year -- although it means that the winner's home broadcaster actually incurs heavy expenses as a result of winning and this has led to suggestions that some nations deliberately choose substandard acts so as to ensure they do not win. Many pop singers and groups have begun the path to fame with a win at the contest. However, ABBA and Celine Dion are the only contest winners to have had significant international success.

The musicians and songs selected for the contest tend towards very conventional "bubblegum" pop, and voting patterns often show more about the ethnic prejudices and politics of various European nations than to the quality of the music. For instance, British and French entries tend to do very poorly in each other's poll. Turkey and Greece generally snub each other. Turkish acts poll well in Germany due to the large population of Turkish expatriates there. Many viewers of the contest view the event as a combination of camp entertainment and a musical train wreck (a fact played upon in the English-language broadcast with the sardonic BBC commentary of Terry Wogan) and a subculture of Eurovision song contest drinking games and the like has evolved in some countries.

For the 2002 edition, the Spanish TVE[?] created an reality showOperación Triunfo[?] that showed the selection and training of unknown singers. At the end, one of them would be elected by the public to represent the country in the contest. The format was an enormous success in Spain and is being exported. One of the first of these exports was the Irish You're A Star[?], run on Radio Telifís Éireann over Winter 2002/'03 for the 2003 Contest.

Denmark origanly held a song contest for children in 2000 then it organised a Nordic Childrens Eurovision. The EBU saw clips of the show and liked it so decided to create an official Children's Eurovision.

From 2003 there will also be held an Eurovision Song Contest for children called Junior ESC in Denmark.

Since each of the entrant countries casts a series of votes, it is only rarely that a song has failed to have any votes at all cast for it. This is known to English speakers as nul points, after the Eurovision practice of reading out the results in both English and French.
